I thought of that too and took it on a spin up to the mountain the other day. It's a good 25 minutes of mixed hill climbs and mild upgrades and the car only got to about 185 (maybe a little less) on the gauge during the longest climb.
Do you know at what temp the aux fan kicks in? I would have thought it would kick on but it didn't as far as I could tell. In fact, I stopped at the top of one long hill and just let the car idle to see if it would heat up and kick on the fan and it did not.
The leak is not severe enough to lose coolant pressure immediately either. I can let it sit for up to an hour before it appears to have bled off enough to not spit hot water everywhere when i take off the rad cap. Brings up a good point though. I have not measured exactly how long it takes to lose the pressure. Maybe I'll try that just for reference.
